FASTENER-SETTING IEACH-ELTE.

' L .n r 2. L13Q4 Specification of ett s aten Application filed December 9, 1912.

To all whom it may concern:

Be it known that I, TYVALTER SHAW, a citizen of the United States, and residing at Dedhein, in the county oi Norfolk and State of Massachusetts, have invented certain linproveinents in Fastener-Setting Machines, of which the following description, in connection with the 'accompnnying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures, i

invention relates to machines for setting; fasteners such as eyelets in sheet meterial and one of its objects is to provide a 1nechine by t 1e use of which blind or invisible eyelets may be set in the uppers of boots and shoes.

In setting blind eyelets in a shoe upper the outer pert of the upper is perforated and the eyelets are set in e pert oi the lining, or facing stay which is stitched to the lining, in register with the holes so punched. In the finished shoe, therefore,nothing is visible but a series oi? perforations through which the lacing passes. These perforctions are reinforced and kept from pulling out by the blind or invisible eyelets set in the material directly beneath them.

Heretofore blind eyeleting has been carried out by punching th eyelet holes through both parts of the upper in one mechiiie by the use of e singleqounch and then setting the eyelets in the lining or lgcing stay a separate operation by hand "or by a foot power eyeleting machine. This has not in all cases proved satisfactory for it has necessitated the formation of holes in the outer leather pert o'f'the upper of diameter at least as great as the eyelet barrel, Whereas smaller holes would suffice for the passage of thelccing and present a more attractive appearance.

In accordance with one feature of the in= veution, accordingly, independent punches are provided, one for punching the eyelet holes and the other for punching the holes for the lacing the outer part oi the upper.

It is believed that prior to this invention blind eyelets have never been set by a power peretecl machine equipped With'independent punching devicesfor operating on the lining and outer parts respectively;

,depenclen Serial Info. 35,758.

Another of the invention consists in the provision of e thin Work separating member adapted to be inserted between the partially attached parts of a shoe upper and serving to separate that part which is to be punched only from that-pert which is to he punched and eyeleted. An important edventage of such a seperetine member is that the two parts 01"" the upper may be fed across its opposite feces and any desired or different operations may he performed in Without diidculty upon the parts of is work so separated. For example, as herein shown, each pen is operated upon by two separate tools, e punch and an independent setting die on one part and a punch and a feeding device on the other part.

In the machine herein shown an upsetting die is mounted upon one side of the Work separating member and a setting die is ar ranged to cooperate therewitlifor inserting endclenching successive eyelets in the pert of the upper which is fed across the upset ting die. The work separating member upon its other side is made smooth so that the other side of the upper, which is to be punched boy, can be fed across it Without obstruction.

Previously to the settin operation the pert of the upper to he eyeleted is punched nd, as herein shown, the other part of the i upper is punched at the seinev tirn'el Aselreedy stated, these operations are effectedv by separate punches arranged to operetelon the different p rts.

In the embodiment of the invention herein disclosed the Work separating device may such,

be utilized with good advantage as a cutting forexample, as a spindle which is arranged to be moved oppositely to the setting die and to engage the smooth side of the work engaging member when the setting die is 'moved'toward the upsetting die.

engaging each part'of the upper and moving it exactly the same distance in the feeding operation. In the embodiment of the invention herein shown this is effected by employing the two setting dies to feed that part of the upper in which the eyelets are set' and by employing the supporting spindle as a feedin device for the other part of the upper. ,u'ring the feeding movement, which is imp t ed to the work by moving the setting devices and supporting spindle laterally, the'setting dies remain in engagement with the' 'iclenched eyelet while the supporting spindle remainsin the hole punched in the other part ofthe upper.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the ac companying drawing, in which- Figure 1 is a view in side elevation of so much 'of the machine as is necessary to understand tlie operation of its different elements; "Fig. '2- 1s a plan view on a smaller scale than'jFiigrf l of the work. guiding and separating members showing a shoe upper,

partially. supplied with blind eyelets; F igs'. 3 to 5 illustrate successive steps inthe operation of'the machine; Fig; 6 is a sectional view of aport on of the work separating member showing the upsetting die.

The invention is herein shown as embodied in a duplex eyeleting machine of the type disclosed in I Letters Patent of the United StatesNo. 934,066, granted September 14, 1909 "on an application of George Goddu. 'As in themachine of said patent,

the forked head 10 is provided with bearingsforoppositely arranged punches 14: which cooperate with a double faced cut ting block 22 set in an intermediate member 16. Inthe present embodiment of the invention this intermediate member has the function of awork separating device, being adapted to be slipped in between the partially attached parts of a shoe upper as shown in Fig. 2; The head 10 has also bearf of Contact with the Work:

ings for twoloppositely arranged plungers' 12 of which the upper one carries a setting die and spindle 13 and the lower carries a feeding and supporting spindle 34. Onthe A lined quarter'i's upper face of the work separating member is arranged an upsetting die 23 disposed in the path of the upper plunger 12 while upon its lower side the work separating member is smooth and adapted to be engaged by the flat end of the spindle 31. The upsetting die may be arranged in the work separating member in any desired manner but as herein shown it is formed on the upper surface of a removable plug, retained in position in the Work separating member by a transverse screw 18 as shown'in Fig. 6.

A movable raceway 36 is arranged to swing into and out of line with the spindle of the setting die and delivers successive eyelets thereto which are then inserted and clenched against the upsetting die when the plunger 12 is forced downwardly. At one side of the work separating member 16 is disposed stationary 'work guiding means. This includes a hook shaped'supporting plate 19 carrying yieldingly'mounted presser feet 17 which act topress the work smoothly against the opposite sidesof the plate 19 and direct it to the punches and the set. An edge gage 21 may also be conveniently mounted upon the plate 19.' This plate is secured to and projects outwardly from'a part of the machine frame, as fully shownin said patent above mentioned.

The head 10 is arranged to have movement in two directions at substantially right angles to each other and any suitablemeans maybe employed to effect these movements, for example, the cams and levers shown in Patent No. 934,066. The first movement of the head is toward the rear for the purpose of bringing the set 12 and feeding spindle 3% into alinement with the holes in the work previously formed by the punches. The second movement is a transverse movement which draws the worktoward the left (Fig. 2) and so feeds it from one e'yeleting posi tion tov the next.

The punches 14: and the plungers 12 are forced toward the work separating member 16 by the levers 15 operated by cams, not

shown, and are retracted by the ten .ion

springs 28 and 30 which operate on l fting levers 2 6 and 2.4. When the setting; die is forced against the upsetting die in clcnch ing an eyelet the center spindle yields inwardly within the body of the upper plunger 12. lVhen the lower plunger is forced toward the work separating member the spindle 84: bottoms in the plunger and so rigidly supports the work separating member ..against the thrust of the setting-die and at the same time holds the end of the plunger inserted as shown in Fig. 2, with its outer finished part below the plate 19 and below the work separating member 16. The facing stay and lining lie above these two members. In initial position the punches and plungers occupy positions remote from the work separating member as shown in Fig. 1. The Work is positioned with the point at which the first eyelet is to be set in line with the punches and the machine is thereafter started. The punches are first forced toward the opposite sides of the work separating member and both parts of the upper perforated as shown in Fig. 3. Then the punches are retracted and While the work remains at rest the head 10 is moved rearwardly bringing the setting die and spindle into line with the previously punched holes in the Work. At about the same time the raceway is moved so to carry the endmost eyelet into alinement with the center spindle of the setting die, as shown in Fig. 4. In the next step in the cycle ofoperations he setting die and spindie 3% are forced toward the work separating member while the raceway is withdrawn. he setting die, therefore, inserts the eyelet through the hole in the facing stay and clenches it against the upsetting die while, at the same time, the reinforcing and feeding spindle enters the hole in the part of the upper below the work separat ing member and engages the lower side oi? the member, as shown in Fig. 5. With the setting die and spindle in the same position the head is then moved. transversely to feed the work and finally the die and spindle are retracted and the parts returned to initial position.
